Solar generator kits · 481Wh to 2,400Wh
A kit is one power station plus one foldable solar panel, bought as two items: 481–2,400Wh of storage, 600–3,300W of AC output and a 220W or 450W panel. Three tiers, one per job — camping, high-draw portable work, and a modular system you can grow.
Entry
Weekend campers, CPAP users and photographers — anyone who needs one night of power and wants it back before the next one.
220W against a 240W ceiling
3.0–3.4 hours to full · clear midday sun
Clear midday sun. Overcast pushes this past 13 hours, which is why the P600 keeps AC charging as its primary route.
High-power portable
Contractors, van builds and long off-grid stays that need 2,400W of AC and can wait two sun-days for a full bank.
450W against a 1,200W ceiling — voltage, not watts, is the limit
6.7–7.6 hours to full · clear midday sun
Two sun-days for a full bank. Plan AC charging as the turnaround and solar as the daytime offset.
Modular entry
Power-tool users who want 3,300W now and the option to stack 2.4kWh modules later instead of replacing the station.
450W / 42.02V inside 1,000W / 100V
7.4–8.4 hours to full · clear midday sun
Two SP450s in series bring the same bank to roughly 3.7–4.2 hours if a one-day refill matters.
Recharge times use the same 85% panel-to-battery efficiency as every other figure on this site, and come straight from the published matrix on each panel page. The total is the station price plus the panel price — there is no bundle discount, and no bundle markup either.
The three stations from the kits above, against every panel configuration we sell. Watts are nameplate totals for the whole string; volts are the summed open-circuit voltage, which is what a station actually sees before its controller starts drawing. The star marks the pairing each kit ships with.
| Power station | Battery | Solar input | 1 × SP220 220W · 21.06V | 2 × SP220 series 440W · 42.12V | 1 × SP450 450W · 42.02V | 2 × SP450 series 900W · 84.04V |
|---|---|---|---|---|---|---|
| P600 | 481Wh | 240W 12–50V / 12A | Fits | Clipped | Clipped | Over voltage |
| P2400 | 2,160Wh | 1,200W 12–60V / 25A | Fits | Fits | Fits | Over voltage |
| G2400 | 2,400Wh | 1,000W 11–100V / 20A | Fits | Fits | Fits | Fits |
"Clipped" means the station stops accepting at its ceiling: the panels still work, you just pay for watts that never arrive. "Over voltage" means the string exceeds the input window and should not be connected. Parallel wiring is a separate case — two SP220s in parallel pull 24.44A, past every SoreinPower input, so a parallel array needs its own controller. The full electrical data and the series-versus-parallel table sit on each panel page: 200W / 220W panel and 400W / 450W panel.
Work backwards from what you burn, not forwards from what the battery holds. Three steps, plus the factor of 1.5 that covers the gap between a panel's label and what actually reaches the battery.
Watts × hours for every device, then sum. A mini fridge averaging 60W over 24 hours is 1,440Wh; a laptop at 60W for four hours is 240Wh.
Four hours is the planning figure for most of the continental US, five on the Gulf coast and in the desert Southwest, three in a northern winter. That division gives the watts the array has to deliver while the sun is strongest.
Only about two thirds of a panel's rated watts reaches the battery once heat, angle, soiling and charging losses are counted, so the nameplate figure is 1.5× what step two produced. Then compare it with the station's solar input ceiling and take the lower number — anything above the ceiling is money spent on watts that never arrive.
| Scenario | Typical load | Daily use | Array must deliver | Panel to buy |
|---|---|---|---|---|
| Camping | Lights, phone, camera, laptop | 500Wh | 125W | 1 × SP220 (220W) |
| Home outage | Fridge, router, lights, phones | 1,200Wh | 300W | 1 × SP450 (450W) |
| RV / cabin | Fridge, coffee, router, TV | 3,000Wh | 750W | 2 × SP450 (900W) |
500Wh a day divides to 125W of array, and 1.5× that is 188W — which is why the entry kit ships with the 220W SP220. 1,200Wh a day lands on 300W, 450W with the factor, and that is the SP450. 3,000Wh a day asks for 750W, or 1,125W on the label; no G Series main base accepts more than 1,000W, so the answer caps at two SP450s and the AC charger covers the shortfall.
Kit questions
Buying separately, mixing brands, cloud cover and what the hour figures really mean.
Yes. Every item on this page is its own SKU — there is no bundle packaging and no bundle price. A kit is our recommendation of which panel goes with which station, and the cart simply shows two lines instead of one.
As long as the string stays inside the station's voltage window and the total stays under its watt ceiling. A G Series main base accepts 1,000W at 11–100V, so two SP450s land at 900W and 84.04V with room to spare — the modular kit is the one tier where a second panel is a real option later. The P600 caps solar at 240W, so a second panel there would be wasted money. The pairing matrix above covers every combination.
Usually yes, if its open-circuit voltage sits inside the station's input window and its current stays under the amp limit. Both panels ship with MC4 connectors on a factory lead plus an adapter cable covering DC5521, Anderson, XT60 and aviation M16. Check Voc first — a string that exceeds the window can damage the charge controller, not just underperform.
The SP220 returns 150–170W in clear midday sun, 60–100W under thin cloud and 10–40W in flat overcast. The SP450 goes 340–385W, 135–225W and 20–90W across the same three conditions. Output never stops, but below thin cloud neither panel refills a station the same day — that is when the AC charger earns its place.
The same panel with a different cell batch: identical 2,035 × 600mm sheet, identical 505 × 600 × 17mm folded size, identical 7.2 kg. The SP220 runs 25% cell efficiency against 24%, which is where the extra 20W comes from without a bigger panel. Pick the SP220 when the panel count and packing space are fixed; pick the SP200 when you have room for a second panel and want the lower cost per watt.
No. Every SoreinPower station has a built-in MPPT controller, so the panel connects straight to the solar input. A separate controller only enters the picture when you wire panels in parallel, which pulls more current than the station's input accepts.
No, that figure is equivalent full-sun hours, not clock hours. A clear day delivers four to five of them in most of the continental US, so 7.4–8.4 equivalent hours is roughly two calendar days. Only the entry kit at 3.0–3.4 hours actually finishes inside one day.
